CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application Ser. No. 62/427,327, filed on Nov. 29, 2016.

BACKGROUND

User devices such as smartphones, tablets, wearable devices, etc. are ubiquitous in society. Many users of such devices may want to use the devices to process purchases, including purchases made via a point-of-sale (POS) system or device.

Such POS devices may not include up-to-date communication features that allow for interactions with the user devices. In order to provide such features, merchants must typically purchase a new POS device at considerable expense.

Therefore there exists a need for a device that is able to provide advanced communication capabilities to existing POS devices.

SUMMARY

Some embodiments may provide a consumer interaction module that may be able to interact with a point of sale (POS) terminal. The module may be a stand-alone device that is implemented using a standard packaging. For instance, some embodiments may be housed in a package that is able to fit a subscriber identity module (SIM), secure access module (SAM) card slot, MicroSD slot, universal serial bus (USB) socket, etc.

Such a package may be fully or partially “insertable” into an existing slot or receptacle associated with the POS terminal. Throughout the present disclosure, the term “insertable” may refer to such packages that are able to fit at least a portion of the housing or package within an existing receptacle (and utilize various resources associated with the receptacle). Thus, for instance, the module of some embodiments may include connectors that are able to supply power to the module, enable communication with the associated terminal, and/or otherwise interact with the terminal (and/or other devices).

The consumer interaction module may include elements such as a controller, memory, and various communication features. Such communication features may include, for instance, wireless transmitters and/or receivers, antennas, interfaces, etc. Such features may enable, for instance, wireless communication capabilities (e.g., Wi-Fi, Bluetooth, etc.) that are not available to the terminal itself.

The communication features may allow the consumer interaction module to communicate with the terminal via physical connectors associated with the slot or receptacle. In addition, the communication features may allow wireless communication among the consumer interaction module, terminal, user devices, servers, and/or other appropriate components. The communication features may allow interactions with various user device applications.

The consumer interaction module may allow for various usage scenarios among the terminal, user device(s), and server(s). For instance, the consumer interaction module may facilitate payment processing by receiving a payment request from the terminal, delivering the request to a user device, receiving payment authorization from the user device, and verifying the transaction with the server. In addition to payment processing, the consumer interaction module may allow administration of rewards or loyalty programs, advertising, and micro positioning (determining locations of user devices relative to the module).

The preceding Summary is intended to serve as a brief introduction to various features of some exemplary embodiments. Other embodiments may be implemented in other specific forms without departing from the scope of the disclosure.

I. Hardware Architecture

FIG. 1 illustrates a schematic block diagram of a system 100 including a consumer interaction module 110 according to an exemplary embodiment. As shown, the system may include the secure access module (or consumer interaction module) 110, terminal(s) 120, user device(s) 130, server(s) 140, and a set of accessible networks 150.

The consumer interaction module 110 may be an electronic device and may include a controller 160, memory 165, and a communication module 170 that may include a terminal interface 175, an antenna 180, and a network interface 185.

The controller 160 may include electronic circuitry and/or discrete devices (e.g., microprocessors, digital signal processors, application specific integrated circuits, etc.) that are able to execute instructions and/or manipulate data such that the controller is able to direct the operations of the various other elements of module 110, as needed.

The memory 165 may include circuitry and/or devices that are able to receive, store, and/or provide instructions and/or data from/to the controller 160 and/or other elements of the module 110, as needed. At least some portion of the memory 165 may include cryptographic memory that is able to facilitate secure interactions with the terminal 120, user device 130, server 140, and/or other devices or systems.

The communication module 170 may allow the consumer interaction module 110 to communicate with various other components, such as the terminal 120, user device 130, server 140, etc. One of ordinary skill in the art will recognize that various alternative communication pathways may be used than shown. For instance, the module 170 may utilize the network interface 185 to communicate with a user device 130 across one or more networks 150. As another example, some embodiments may communicate with the terminal 120 using an antenna 180 and/or network interface 185.

The terminal interface 175 may include various connections between the module 110 and the terminal 120. Such connections may include physical elements such as contact pads on the surface of a SIM card type module 110, pins that extend from a microSD card type module 110, etc. Such types of connections may be referred to as “physical” connections, and may include, for instance, wired connections, terminal or pad connections, etc. The terminal interface 175 may allow for two-way communication between the module 110 and the terminal 120. Such communication may include, for instance, information related to a transaction, rewards program, payment request and confirmation, etc.

The antenna 180 may allow communication across various appropriate wireless pathways (e.g., Bluetooth, WiFi, RF, etc.). The antenna may include one or more “bends” (e.g., a right angle bend) that allow the antenna to fit within the associated footprint and still provide wireless capabilities that meet the appropriate standards. The antenna may be implemented using various appropriate physical elements (e.g., a trace on a printed circuit board, a section of formed metal, etc.). In addition, the antenna may be associated with various transmitters, receivers, etc. that may generate signals for transmission via the antenna and/or receive transmitted signals via the antenna.

The network interface 185 may allow the module to communicate across one or more networks 150. In some embodiments, the network interface 185 may utilize one or more antennas 180 or other communication pathways to access the networks 150. Some embodiments may provide network connectivity to the interface 185 via the terminal 120 and associated terminal interface 175. Likewise, some embodiments may provide network connectivity via the antenna 180 and an associated user device 130 (in such arrangements, the user device may be connected to the module 110 via a physical interface such as a cable rather than via the antenna 180).

The terminal 120 may be an electronic device such as a cash register, credit card terminal, smartphone, tablet, personal computer, parking meter, vending machine, etc. Such devices may include existing SIM card, microSD card, and/or other appropriate slots or ports that may be utilized to accept the consumer interaction module 110 of some embodiments.

The user device 130 may be an electronic device such as a smartphone, tablet, personal computer, wearable device, etc. that is able to communicate with the module 110. Such a device 130 may server as the terminal 120 in some embodiments. In some embodiments, the device 130 may also provide network connectivity to the module 110.

The server 140 may include one or more electronic devices that are able to execute instructions and/or process data. Such servers may be associated with, for instance, payment processing resources, merchant databases (e.g., rewards databases), advertising databases or resources, etc.

The networks 150 may include various appropriate communication pathways, such as WiFi networks, distributed networks such as the Internet, local area wired networks, cellular networks, etc.

FIG. 2A illustrates a front elevation view of an exemplary consumer interaction module 110. As shown, the module is implemented such that the footprint 210 or form factor of the device matches a SIM (or SAM) card footprint or form factor. Thus, the various contact locations of the SIM card may be utilized to allow communication with a terminal or user device. In addition, the entire module may be sized such that the module is able to be placed into an existing SIM slot. FIG. 2B illustrates a front elevation view of another exemplary consumer interaction module 110. As shown, the module is implemented such that the footprint of the device matches the dimensions of a standard microSD card. In this example, the module includes a portion 220 that firs within the microSD slot as well as a portion 230 that does not fit within the microSD card footprint, as indicated by the dashed lines. Some embodiments be arranged such that the module is able to be fully inserted into a microSD slot.

Such devices may be able to be utilized in (and/or with) various existing systems and/or devices, such as registers, credit card terminals, smartphones, tablets, personal computers, parking meters, etc.

One of ordinary skill in the art will recognize that various other specific footprints or form factors may be utilized (e.g., standard secure digital (SD) cards, miniSD cards, compact flash, memory stick, etc.). Each form factor may be at least partially insertable into an appropriate slot. The various components described in reference to module 110 may be included in various other footprints to provide similar functionality to devices with different types or sizes of insertion slots.

II. Methods of Operation

FIG. 3 illustrates a flow chart of an exemplary process 300 that performs proximate consumer interactions. Such a process may be executed by a device such as module 110 described above. The process may begin when such a module (and/or associated terminal) is powered on.

As shown, the process may retrieve (at 310) information from the terminal. Such information may include, for instance, sales information such as amounts or quantities, item codes, rewards, etc.

Next, the process may scan (at 320) for nearby user devices. Such scanning may including sending a beacon signal, discovery message, and/or other appropriate actions. If no response is received, the process may continue scanning or may end.

If the process determines (at 330) that a response has been received, the process may then establish (at 340) a communication channel with the user device. Such a channel may include a wireless communication channel such as Bluetooth. The channel may be implemented in various appropriate ways and/or using various appropriate resources (e.g., a web browser running on a user device, a dedicated application running on a user device, etc.).

The process may then provide (at 350) the channel to the terminal and user device. Such provision may include, for instance, passing messages back and forth between the terminal and user device, translating messages, parsing message content, generating messages, interpreting messages, fragmenting messages, etc.

Next, the process may close (at 360) the communication channel and then may end. Such termination may be based on receipt of a termination or completion message received from the user device and/or terminal.

FIG. 4 illustrates a message flow diagram 400 of an exemplary communication arrangement that performs proximate consumer interactions. Such message flow may be associated with a process such as process 300 described above.

As shown, the secure access module 110 may send (at 410) a message (a) to a user device 130, which may, in turn, send (at 420) a reply (b). Message (a) may include information related to the module, associated terminal, and/or other appropriate information. The response (b) may include information related to the user device 130, the associated user, and/or other appropriate information. Such messaging may be used to establish a communication channel (e.g., a Bluetooth link) between the module 110 and the user device 130. In some embodiments, the module 110 and/or user device 130 may send additional messages.

Next, the secure access module 110 may send (at 430) a message (c) to a terminal 120, which may, in turn, send (at 440) reply (d). Message (c) may include information related to the user, user device, and/or other appropriate information. The response (d) may include information related to the user (e.g., rewards account information), transaction (e.g., sales amount, list of items, etc.), and/or other appropriate information. Such messaging may be performed using existing connectors of the terminal 120 associated with, for instance, a SIM card or microSD card slot as described above.

The secure access module 110 may then send (at 450) a message (e) to a user device 130, which may, in turn, send (at 460) reply (f). Message (e) may include information related to a transaction, rewards account, and/or other appropriate information. The response (f) may include payment authorization, user identity information, and/or other appropriate information. In some embodiments, the module 110 and/or user device 130 may send additional messages.

Next, the secure access module 110 may send (at 470) a message (g) to terminal 120, which may, in turn, send (at 480) reply (h). Message (g) may include information related to payment authorization, user identity information, and/or other appropriate information. The response (h) may include receipt confirmation, current balance, and/or other appropriate information.

Finally, the secure access module 110 may send (at 490) a message (i) to a server 140, which may, in turn, send (at 495) reply (j). Message (i) may include information related to the transaction, terminal (and/or associated venue), user, and/or other appropriate information. The response (j) may include information related to the user, receipt confirmation, and/or other appropriate information. Such messaging may be used to establish a communication channel (e.g., using an API and one or more networks) between the module 110 and the server 140. In some embodiments, the module 110 and/or server 140 may send additional messages. For instance, in some embodiments, the module 110 may request authorization from a payment processing server 140 before finalizing a transaction.

One of ordinary skill in the art will recognize that process 300 and message flow 400 may be implemented in various different ways without departing from the scope of the disclosure. For instance, different embodiments may perform the operations in a different order, may include additional operations, may omit listed operations, etc. In addition, various operations may be performed iteratively and/or based on various criteria.

FIG. 5 illustrates a flow chart of an exemplary process 500 that processes a payment from a user device. Such a process may be executed by a device such as module 110 described above. The process may begin when such a module (and/or associated terminal) is powered on. In this example, a consumer interaction includes an invoice and payment processing. Different embodiments may be implemented in different specific ways depending on the type of interaction, type of terminal, and/or other relevant factors.

As shown, the process may receive (at 510) an invoice (or other type of payment request). Such an invoice may be retrieved from a terminal such as terminal 120 described above. The invoice may include information such as a listing of goods and/or services, quantities, sales amount, tax amount, etc. The invoice may be generated based on various relevant factors or criteria. For instance, a merchant may scan physical items at a register and begin payment processing. As another example, a user may input a desired selection at a vending machine (or a duration for a parking meter) that may trigger generation of an invoice or payment request. As still another example, a merchant or other provider may enter a total amount into a credit card terminal.

Next, the process may send (at 520) the invoice to a user device such as user device 130 described above. The invoice may be sent across a channel generated by a process similar to process 300 described above.

The process may then receive (at 530) payment information from the user device. Such information may be received via the channel described above. The payment information may be sent based on some input received from a user (e.g., by pressing a “confirmation” button or other user interface element) or may be sent automatically based on proximity. Such payments may be sent based on various user preferences. For instance, a user may authorize a merchant, device, etc. and then payment information may be sent in reply to any validated request (e.g., a user may regularly make purchases from a vending machine and may pre-authorize such purchases up to a specified limit). As another example, the user may be presented with purchase information (e.g., merchant identity, total amount, etc.) and may be required to confirm or otherwise validate the purchase (e.g., by selecting or authorizing a payment method, by tapping or touching the user device to the terminal or other resource, etc.).

Next, the process may send (at 540) a verification request to a server such as server 140 described above. The verification request may include, for instance, total amount requested, payment information received from the user device, etc. In some embodiments, the verification request may be process locally at the terminal (e.g., for store rewards programs, gift cards, etc.).

Next, the process may determine (at 550) whether the verification request has been authorized. Such a determination may be made based on information received from the server in response to the verification request. In some cases, the verification request may be a pre-authorization or other such transaction that is not associated with a final sales amount. In such cases, the verification response may include an approval limit and/or other appropriate information.

If the process determines (at 550) that the verification request should be authorized, the process may then approve (at 560) the purchase and/or otherwise indicate that the verification request has been approved. Such approval may include, for instance, sending one or more messages to the terminal of some embodiments, sending messages to a merchant device, etc. The approval may include a transaction identifier, timestamp, and/or other appropriate information.

Next, the process may send (at 570) confirmation to the user device and then may end. Such confirmation may include, for instance, one or more messages that deliver a receipt or other appropriate information related to the transaction or interaction. The confirmation may also be communicated to the terminal of some embodiments.

If the process determines (at 550) that the verification request should not be authorized, the process may send (at 580) a rejection to the user device and then may end. Such a rejection may also be communicated to the terminal of some embodiments.

One of ordinary skill in the art will recognize that processes 300 and 500 and messaging algorithm 400 may be implemented in various different ways without departing from the scope of the disclosure. For instance, different embodiments may perform the operations in a different order, may include additional operations, may omit listed operations, etc. In addition, various operations may be performed iteratively and/or based on various criteria.

III. Computer System

Many of the processes and modules described above may be implemented as software processes that are specified as one or more sets of instructions recorded on a non-transitory storage medium. When these instructions are executed by one or more computational element(s) (e.g., microprocessors, microcontrollers, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), etc.) the instructions cause the computational element(s) to perform actions specified in the instructions.
